SPECIFICATION forming part of Letters Patent No. 490,010, dated January1'?, 1893.

Application iiled July 16, 1892. Serial No. 440,264. (No model.)

To @ZZ whom t may concern:

Be it known that L JAMES MADISON Denn, a citizen ot the United States,residing at Harlan, in the county of Shelby and State of Iowa, haveinvented certain new and usefullmprovements in Loom-Shuttles; and I dohereby declare the following to be a full, clear, and exact descriptionot' the invent-ion, such as will enable others skilled in the art towhich it appertains to make and use the same.

My invention relates to shuttles which are especially designed to beused in looms for weaving fabric. In handling this class of devices asat present constructed, preparatory to weaving, much inconvenience isexperienced in manipulating the cop or can used for receiving the weft.When either the cop or can is used it is necessary to detach it from theshuttle body and place in the filling machine, and when filled and readyto replace, the wet t must be inserted through the shuttle eye, usuallyby tool called the shuttle hook.

The present invention obviates the inconviences above specified bydiscarding the use of inside attachment, the shuttle body being a plaintube.

The improvement consists of the novel features and the peculiarconstruction and coinbination ofthe parts which will be hereinafter morefully described and claimed and which are shown in the annexed drawingsin which;

Figure 1 is a central longitudinal section of ashuttle embodying myinvention. Fig. 2 is a detail view of the tension bar. Fig. 3 is adetail view of the shuttle head detached; the tension bar and springbeing removed to the better show the structural arrangement of the saidshuttle head. Fig. l is a detail View showing the manner of filling theshuttle. Fig. 5 is a detail View showinga modified forni of tension bar,and a set screw for regulating the saine.

The shuttle is composed, essentially, of the shell or body portion Awhich is hollow or tubular, being provided with the bore o, and the capB, the latter closing the open end of the bore o and carrying thetension device. The shell or body portion A may be of any desired forniand size and is pointed at one end, the other end tapering slightly andbeing closed by the tapering head B. The shell or body portion A ishollow or provided with a bore a, the latter being closed at one end andopen at the opposite end, the open end being provided with a depressionor notch g in one side which is designed to receive the free end of thetension bar C. The head B for closing the open end of the shuttle bodyis made tapering, and is provided with a reduced portion b which isdesigned to enter the open end of the bore c and closethe same and givestability to said head. The notch ZJ provided in the inner end of thereduced portion Z) is adapted to receive and permit of the free workingsof the tension bar C, and the transverse groove or channel b2, alsoprovided in the reduced portions b is designed to receive the spring CZwhich is pivotallyT supported between its ends, one end of said springbeing adapted to press upon the tension bar C to create the desiredtension, and the other end being constructed to obtain a bearing uponthe inner side of the shuttle body A opposite the depression g so as toretain the spring in proper working position. The tension bar C ispivotally supported at one end at the inner end of the notch b and itsouter portion is adapted to work in said notch b and the depression ornotch g, and is preterabl y provided with parallel prongs c at its freeend between which the weft thread is adapted to pass, said prongspreventing said weft thread from slipping from engagement with the freeend of said tension bar C. These prongs c are adapted to enter suitabledepressions j provided in the shuttle body. lVhile itis preferred tomake the tension bar C and spring d in separate pieces, manifestly thetwo parts C and d may be integrally formed, as most clearly shown inFig. 5. The operation will be precisely the same as that described forthe parts when constructed separately.

The shuttle may be iilled in any desired manner but it is preferred toprovide the means shown in Fig. 4 which consists of the tapering tube Mthe smaller end being constructed to enter the open end of thc shuttlebody, and the drawing rollers N which are adapted to receive the weftthread and force the saine through the tube M into the shuttle body.VThe shuttle being filled in any desired manner, the end of the weftthread O is drawn across the depression g which practiyfm, serves tocompensate for wear and maintain a tight fit between the cap B and theshuttle body A. This form of tension bar f dispenses with a separatespringy and -embodies the same in its construction.

f Having thus described my invention, what I claim, and desire to secureby Letters Patent 1sl. The combination with a hollow'shuttle body openat one end, of ra cap adapted to close said open end, a tension bar, anda spring serving to secure said cap to the shuttle body, and create atension on the saidftension bar substantially as set forth.

y2. The combination with a hollow shuttle body opened at one end, andhaving depression g, of a cap adapted to close the open end of saidshuttle body, and a'tensiony bar oarried by said' cap and adapted toWork insaid Thetension bar shown in Fig. 5 ha'sa' depressiongsubstantially as and for the purpose set forth. f

3. The combination withr a hollow'shuttle body, and a cap for closingthe opened end of said shuttle body, of a tension bar carried by one ofthe said parts and provided with approximately parailel prongs b to giveproper direction to the weft thread and retain the f same in properposition, substantially as described. f* ,c

4. The combination with a hollow shuttle body having one end open andprovided with depression g, of a cap having a reduced portion to enterthe open end of said shuttle body and provided 'with notch b andtransverse channel b2, a tension bar pivotaliy con-
